The tension had been building for weeks. Little glances, lingering touches – the unspoken desire hanging heavy in the air. I knew it was wrong, so wrong, but the thought of her, my stepsister, consumed me.
She walked into my room, ostensibly to borrow a shirt. But the way she lingered, the way her eyes met mine, it was an invitation. A dangerous, irresistible invitation.
"Is everything okay?" I asked, my voice barely a whisper. She was wearing one of my old t-shirts and nothing else. Her natural tits strained against the fabric and the urge was overwhelming.
"I don't know," she breathed, taking a step closer. "Is it okay to want this?"
Before I could answer, she was in my arms. The kiss was raw, desperate, a release of pent-up frustration. We stumbled onto the bed, clothes flying. Her perfect body was even more breathtaking up close. The moment she straddled me, becoming a sensual girl on top, I was lost.
Her big tits bounced with every move, the bouncing boobs driving me wild. She took control, riding me hard, loud moaning escaping her lips. It was a cowgirl riding fantasy come to life, except this was real, this was forbidden, and it was hotter than anything I'd ever imagined. The missionary position quickly led to her taking back control and going wild! I gripped her hips, urging her faster, deeper. I had never experienced anything like this with rough sex. She loved it.
I knew I couldn't hold back. The pleasure was too intense. As I felt myself nearing the edge, I whispered in her ear, "I'm gonna cum."
Her eyes widened, and she nodded eagerly. "Do it," she gasped. "Cum inside me."
A moment later I pushed a torrent of cum, giving her an amateur creampie she won't forget.
I knew this was wrong, but at the time, it felt so right. The after-effects will be on our minds for a long time.
